FD5703 24th capacity.

[Nigelnaturist]

Well I got my new cranks from Spa some TD2 touring cranks with two of Spa Cycles own Zircal rings a 50th and a 38th, I already have a 26 and 28th inner.
I was curious to if the FD5703 could manage a 24th capacity, so I assembled it with the 26th inner, and works fine so far, though had very little chance to try out the inner ring. I was a bit worried the 26th may be to small and the chain might want to keep derailing, this now gives me on my 12-27 cassette a range of 25.3-109.6" I will probably change it to the 28th over the weekend as even 25" is very low even for me.

Well I have been reading on other forums that a 24/38/52 has been achieved on similar kit.

Just reading, I was more looking for future intentions of the triple, as you are aware the new 105 is only available in a double 11sp, and because it caught my eye being similar to what I have just done i read it.

Polished alloy square taper chainsets are simply beautiful. That would be at home on the wall of an art gallery.

Not sure the O.H. would appreciate it though

Bit better boxed than mine

I'm keeping the box to reuse when I sell my old chainset on eBay!

What did yours come in then?

 

[Nigelnaturist]

I actually just bought the cranks and two rings, having already got a couple of pretty unused inner rings, so the rings came as they do and the cranks with loads of plastic wrapping and card, it was well packaged, just yours looks better presented, but being a crankset, you would hope so

 

[Nigelnaturist]

Well after a couple of more consistent rides, I can say that the chain stays on the inner when selected, shifts well, and I am considering changing from a 12-27 to a 12-25 cassette as the 26x25 is still lower than my 30x27 was, so I have a really close grouped double with good climbing gears.

@ColinJ out of interest what is your inner I can't make it out. I think it looks like 28

Looks great. Those Chainrings are well finished.

Yes - it is a 28. The chainset is 48/38/28 so I gave up my 53/13 top gear (which I hardly ever used) to get a much more useful big ring which will take me to 31 mph (50 kph) at my favoured cadence, I can do about 10-15% above that for short bursts if I want to, but more often that not I just get into an aero tuck for fast downhills and do 40+ mph freewheeling.

The changes between rings are much nicer than they are with the bigger steps on my Basso: 28->38 vs 26->39 and 38->48 vs 39->52.

@fossyant if you mean mine, I was quite surprised, outer £20 middle £15 the inner are £10 in zircal 7075 T6, the cranks were not finished so well lots of little burs but usable for £22
